This week Parks
Vic released the first map of the parts of the Marine National Parks.
Apparently the first maps of the areas were done by Matthew Flinders
about 200 yrs ago, and now Point Addis has been completed - it seems
he was about right. The four other deep water areas are next on
the list.
To map the habitat,
three things are needed: Depth (measured every 10cm), Texture (measured
by snippets) from the sonar, and finally tow video - where the very
long videos are are made and watched.
And what about
those algae that form calcium carbonate balls by depositing it within
their cell walls, and as they die, the balls get bigger
